I need to make a place for only me. sort of like a sanctuary. But i don't really want to cut wood or anything.

Question

A place where i can be alone without actually building it i'm only 11.

Answer 1

Is there a part of the basement you could use?  Attic?  That old van sitting in the driveway that no-one uses?

Answer 2

Try a tent, or some tarps strung from trees.

Answer 3

Do you have your own room?  You can turn that into your sanctuary by surrounding yourself with things that you find comforting and make you feel at peace and harmony with yourself and your environment.  Otherwise you could get a really big cardboard box and cut windows in it and make that your little room outdoors.  Be creative- you'll think of something.
